In Traktor Pro 4 you have command and the possibility to make a command 2 tag for extra important information.
I am from the Netherlands so Command is Opmerkingen in Mp3 tag, and the command 2 is Opmerkingen 2 in my Dutch version for Mp3 tag.
How can i make an extra tag that corresponds with the command 2 line in Traktor
Take a file for which your player shows all the data and load it into MP3tag.
Select it and open the extended tags dialogue Alt-T.
Check whether the data is visible in the list of tag fields.
Remember the tag field name(s) for Comment.
Follow the documentation how to customize the tag panel:
Could it be that it is some kind of a COMMENT and something like a COMMENT_2 field?
Unfortunately, in my own last Traktor 4 test, this kind of COMMENT 2 was not available in Mp3tag.
Yeah LyricsLover is right. Comment2 is a Traktor only field. It is stored in Traktors Collection .nml, and not in the actual music file.
